Whether we are imagining microbes or mammoths dinosaurs or diatoms, molecules or stars, people of all ages are fascinated with the very large and the very small. New technologies have enabled scientists to investigate extremes of science previously unknown. An understanding of scale and scaling effects is of central importance to a scientific understanding of the world. Help your middle and high school biology, Earth science, chemistry, physics, and mathematics students develop quantitative evaluation with Extreme Science. Authors Gail Jones, Amy Taylor, and Michael Falvo offer a detailed look at types of scale, measurement, powers of ten, estimation and models of scale, surface to volume relationships, limits to size, and behaviours at different scales. The investigations in this book are designed to help students develop a comprehensive and flexible sense of scale through experiences with the quantitative units and tools of science. Investigations build on our research that has documented how people learn scale. To aid in comprehension, Extreme Science uses the 5Es (engage, explore, explain, extend, and evaluate) to illustrate each topic. By using this learning method, the activities help students learn to invent scales, develop benchmarks, estimate, and apply body rulers (estimating using fingers, arms, or pacing off distances). In doing so, students will come to understand scale on an intrinsic level and will appreciate that no problem is too big or too little to be scaleable. Comprehending scale at the largest and smallest levels is where a quantitative understanding of the world begins.The study of science at the extremes of size often involves creating and testing models of science phenomena. ... These models can be physical, such as a Styrofoam ball model of the solar system; virtual models such as animations; or mathematical models ... When they work with a model, it is important for students to have an understanding of the proportional relationships that exist between the size ofanbsp;...
